fire is hot because of the complex sequence of chemical reactions between a fuel and an oxidant that produce heat and/or light. It is an 'exothermic' reaction in that not every oxidation reaction occurs at a fast enough rate to produce heat. Take rust, for instance. It is an oxidation process that occurs too slowly to produce heat.

Rapid combustion is a form of combustion in which large amounts of heat and light energy are released. This often occurs as a fire. This is used in a form of machinery, such as internal combustion engines, and in thermobaric weapons.

Fire is from Burning. Burning is combining with oxygen This chemical reaction is exothermic. That is, it gives out energy, part of which is radiated as heat. Hence, fire appears to be hot.

good question...!!
fire is hot because of series of chemical reactions which release energy...that is these reactions are exothermic in nature..
now the question where does this energy comes from? still following the "law of conservation of energy" that is energy cannot be created or destroyed..this energy comes from the formation of new bonds .for example carbon from wood combines with oxygen to form co2..which is an exothermic reaction..it is because of this energy that fire is hot!!!
answer got TOO LONG I GUESS...

It's the transition of energy!
Burning something or chemistry speak - a combustion reaction causes chemical energy which turns into heat and light energy.

Remember the thing about
"energy can neither be created nor destroyed".

Fire is combustion, a form of reaction.
"new" susbstance are formed by tis reaction.
However some of the energy is converted to light and heat.

Let me guess. It releases some energy ?

Let's wood's fire. Wood's carbon combines with air oxygen, giving CO2 + energy. There are energy exchange in all chemical reactions, this one is exothermic. Good for us ;-).

Rapid oxidation is an exothermic reaction, so it gives off heat.
